摘　　要：为研究交趾黄檀不同家系在三亚地区生长的差异,以期初步选出优良种质为进一步的遗传改良提供基础。以来自中国林业科学研究院热带林业研究所26个家系的交趾黄檀幼苗为研究对象,在三亚地区开展生长试验研究。结果表明,监测1年后,26个交趾黄檀家系在三亚地区均能正常生长,家系2、4、9、16和18苗木成活率较高;家系1、10、11、13和22苗木生长量较快,苗高净生长量在0.9 m以上,地径净生长量在12 mm以上。聚类分析将26个交趾黄檀家系分为4类,可用其成活率、生长量作为交趾黄檀引种衡量因子之一。To provide a basis for introduction to appropriate regions and to further improve genetic traits for Dalbergia cochinchinensis, the growth of different families of D. cochinchinensis in Sanya area were studied. The growth experiment was conducted with 26 families olD. cochinchinensis in Research Institute of Tropical Forestry, Chinese Academy of Forestry. The results showed that after one year, 26 families of D. cochinchinen- sis were grow normally in Sanya. The survival rate of 2,4,9,16 and 18 seedlings was higher, and the growth of seedlings of families 1,10,11,13 and 22 were faster. The high net growth was above 0.9 m, and the net ground diameter growth was above 12 ram, respectively. Clustering analysis classified the 26families into four groups based on their survival rates and growth. The survival rate and growth index could be used as one of the factors for the introduction of D. cochinchinensis.
